7 Be it known-that I, FREDERICK Bao- MANN, a citizen of the United States and resident of Pittsburgh, in the county of'Allegheny and'State of Pennsylvania, have in-. 2 venteda new and useful Improvement in Rail Anchors; and I dohereby declarethe following to be a full, clear, andrexact description thereof.

' My invention relates to rail anchors and i particularly to those devices of the type adapted to be secured to. railway rails and to bear against the sidesof the 'cross'ties to prevent creeping of the rails.

One object of my invention is. to provide a device of simple form andwhich may be 1 cheaply made.

' fAnother'objectof my device to provide an anchor whichzmay be composed sub- 'stantially entirely of rolled steel plates blanked from stock material by dies,x at"one unchin 0 eration; P a

r' Still another ob ect' is tor pro vide a uni- "tarystructure that may be ma-rketed: and

freely handled withoutthe parts becoming misplaced-or lost. v

i A further object of my invention provide a-rail anchor ofv simple and cheap construction' which will grip and hold the edges of the rail bas with increased force upon the application of'creeping 'straing y 1 QSomeofthe "forms which my. invention may take are shown in the accompanying drawing, :wherein Fig. 1. is an lelevational 'viewofia portionof arailroad rail showing one stage of the application of the anchor'to' the rail;fFig. 2':is a'similar View showing the anchor completely in place; Fig. 3 is a plan view of the device of Fig. 2, and Fig. 4 is a plan view of a modified form of anchor. v

The anchor is shown as applied to a fragmentary portion of a railroad rail 5, and comprises two-plates 6 that are preferably secured together at one end by a rivet or bolt 7 and at their other ends are perforated to receive a pin 8 that serves as a pivot for a clip or'dog 9. The pin 8 is enlarged at its mid-portion so as to form shoulders against which the inside faces of the plates 6 bear. The pin 8 therefore serves not only as a pivot for the clip 9, but acts as a spacer for holding the adja- 11 are then.

, The pin 8 and the clip 9 are held in The plates are prefefbld cold stamped from rolled steel; and provided with Tprojections l0, that' are inclinedion their lower edges to closely fitithe upper surface of the rail-base, The upper f edgesvofthe body portion of the plates 6 are, cut away slightly'as indicated at 6 so that when the/anchor-{is locked in, position as shown in ,Fig.

2, the .partsare' all maintained -,under tension. The plates are also. provided, wit h projections llffor engaging andgripping oneedge of the rail baseaj Theproj'ections 10 are; undercut a distance gsufiijcient to. permit driving. of the plates; endwise against v1 the edge .of; the rail base and cause; the proj cti p he aii base F th rm e, the out out p r ion permits. the? anchor. to adapt itself to rail, bases-10f;yarious;;widths.

Before'the clip -9; is fdriven inwardfrom the position I shown in dotted lines in, Fig.

2 i to that shown in 1111. lines, theplatesy 6 re' o d la e lyf f h ra l u t t e-Pt jectionsJO grip. the rail base, The inner vertical edge, of the edges of the projections i o sht in w g-age n vwith the rail base; at its other. edge, 1; i The forcing of th ecli 9"tQ1lOQl Ql pQSltion closes the gap at 6 since the plates will yield somewhat, thus providing tension for tightly holding the clip in place. The shortest radius of the clip 9 with respect to its pivotal axis is approximately at the point 12, so that as the clip is driven from the position indicated in dotted lines in Fig, 2 to that indicated in full lines, an over-the-center action is secured that assists in maintaining the clip against accidental displacement from its locking position.

In Fig. 4 I show an anchor provided with side members 6 that are formed inte rally,

rately as in Fig. .3. The outer end of this form of clip is offset slightly to permit of the binding effect under creeping strains above referred to. In boththisformof device and they form shownin ,Fig. 8, .v the gripping lugs are offset in a direction longitudinally of the rail,,so that, when the plates aredyingagainst the tie and creeping strains are imposed thereon,there Will be a tendency for the anchor to twist and grip the edges of the rail base more firmly.

I claim as my invention:. U

1. A rail I anchor comprising gripping plates for transverse disposition beneath a rail and each provided with an overhanging rail base gripping jaw at one end, and at itsother end with a vertically disposed gripping jaw, the plates being secured together at their first namedends, and at their other ends-provided with means for supporting a rail-engaging clip.

2. A rail anchor comprising gripping plates for transverse disposition beneath a rail and each provided with an oyerhanging rail base gripping jaw at one end and at its other and. with a vertically disposed 'grippingjaw, the plates being secured to gether in flatwise engagement at one end and spaced apart at their other ends. I

3, rail anchor comprising gripping plates for transverse disposition beneath a rail and each provided with an overhanging rail base gripping jaw at one end and at its other end with a vertically disposed grippingjaw, the plates being secured together in flatwise engagement at one end i and spaced apart at their other ends, a pivot' pin egi-tending across the last-named space,

and a locking clip supported by said pin. A A rail anchorcomprising-plates havinglongitudinally disposed gripping jaws adjacent to one end thereof and vertically :disposed grippingjawsfadjacent to their other ends, the first-namedgripping jaws being undercut so that the distance between "the rear wall of said undercut portion and the inner vertical wall of the second named 'gripping jaws is greater than the norm al width of the rail bases; with which 'the anchor is to be employed, and the'iirstnamed gripping jaws having longitudinally inclined gripping surfaces,

A rail anchor comprising gripping plates secured together at one point but spaced apart at one end, aligned perforations extending through the platesat said end, a pinextending through said'perforations and secured to said plates, and a movable clip member carried by said pin.

6. A rail anchor comprising gripping plates secured together adjacent to one end and spaced apart adjacent to their other ends, aligned perforations extending through said last-named ends, and a pin having reduced end portions,v seated within said perforations and'an enlarged mid-portion disposed between the plates to serve as a spacer therefon Y'TLA rail anchor comprising gripping plates secured together adjacentto one end and spaced apart adjacent to their other ends, 7 aligned perforations extending through said last-named ends, a pin having reduced end'portions seated within said perforations, an'enlar'ged mid-portion disposed between theplates to serve as aspacer, and a clip member pivotally connected to said mid-portion of the pin. 7 v

8. A rail anchor comprising plate-like portions securedtogether at one end and whose upper edges are adapted to engage the underside of a rail, a longitudinally inclined gripping jaw on said portions, for gripping the top surface of the rail flange, adjacent anchor is to be used.

In testimony whereof I, the said Fnnn- ERICK VV. BAUMANN, have hereunto set my hand. r 1 l FREDERICK W. BAUMANN.
